Sun Java System Application Server Enterprise Edition 8.2 Release Notes

Reassembly failures on Windows. (ID 6291562)


On the Windows platform, with certain configurations and loads, there may be a large number of reassembly failures in the operating system. The problem has been seen with configurations of more than twenty nodes when running several table scans (select *) in parallel. The symptoms may be that transactions abort frequently, repair or recovery may take a long time to complete, and there may be frequent timeouts in various parts of the system.


To fix the problem, the Windows registry variable HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters can be set to a value higher than the default 100. It is recommended that you increase this value to 0x1000 (4096). For more information, see. article 811003 from the Microsoft support pages.
